But if I make a library and distribute it, the receiver could -
unwittingly- change it. But the idea of using '+' to put before and
after the variable name is a good one. I'll do that.

By the way: you can only change sources if you have them. ;-]
Also: changing a source and recompiling is a little bit more obvious -
also for the person doing it- as a setq.

But my understanding of elisp has been amended. That never hurts.
